Forms a border around the image.

Name Type Range Description
Input value inSrc Image Source image.
Input value inTop Integer 0 - Parameter specifying how many pixels in top direction from the source image rectangle to extrapolate.
Input value inBottom Integer 0 - Parameter specifying how many pixels in bottom direction from the source image rectangle to extrapolate.
Input value inLeft Integer 0 - Parameter specifying how many pixels in left direction from the source image rectangle to extrapolate.
Input value inRight Integer 0 - Parameter specifying how many pixels in right direction from the source image rectangle to extrapolate.
Input value inBorderType CvBorderType Border type.
Input value inValue Pixel* Border value if borderType==BORDER_CONSTANT .
Output value outDst Image Output image.
